Dr. Robert Bucknam is a well-known pediatrician, author, and founder of Cornerstone Pediatrics in Louisville, Colorado. He is best known for co-authoring the book series "On Becoming Babywise" with Gary Ezzo. The series promotes a routine-based infant management strategy that focuses on parent-led feeding schedules, sleep training, and baby care, and has been popular among many parents seeking structured guidance in raising their infants. However, the Babywise approach has also faced criticism from some pediatricians and parenting experts who raise concerns about its strict methods and potential impact on breastfeeding and infant well-being. Despite the controversy, Dr. Bucknam remains an influential figure in the realm of parenting literature, particularly for those who advocate for a regimented approach to infant care.
